Data transmission method, communication equipment and storage medium

Abstract

The embodiment of the invention provides a data transmission method, communication equipment and a storage medium. The method is used for reducing the number of cross connections of intermediate nodesin a network, Q first code block streams are obtained in the embodiment of the invention, non-synchronous head areas of code blocks in the Q first code block streams are put into a to-be-sent secondcode block stream, and the coding types of the first code block streams and the second code block stream are M1 / N1 bit codes; wherein one code block in the first code block stream and the second codeblock stream comprises (N1-M1) bits of synchronous head regions and M1 bits of non-synchronous head regions, and the non-synchronous head region of one code block in the Q first code block streams iscarried by the non-synchronous head region of one code block in the second code block stream. Therefore, the code block stream can be multiplexed and demultiplexed on the granularity of the code block, the second code block stream passes through at least one intermediate node to reach the communication equipment on the demultiplexing side, and the intermediate node does not demultiplex the secondcode block stream, so that the cross connection number of the intermediate nodes in the network can be reduced.

Description

technical field [0001] The present application relates to the communication field, and in particular to a data transmission method, communication equipment and storage medium. Background technique [0002] The Optical Internet Forum (OIF) released Flexible Ethernet (FlexibleEthernet, FlexE), which is a general technology supporting multiple Ethernet MAC layer rates. By binding multiple 100GE (Physical, PHYs) ports and dividing each 100GE port into 20 time slots in the time domain with 5G as the granularity, FlexE can support the following functions: bonding, multiple Ethernet ports Bundled as a link group to support Medium Access Control (MAC) services with a rate greater than that of a single Ethernet port; sub-rates, by assigning time slots to services to support rates lower than the link group bandwidth or lower than a single Ethernet port Broadband MAC services; channelization, by allocating time slots for services to support the simultaneous transmission of multiple MA...

image 3 It exemplarily shows a communication schematic diagram of end-to-end networking where X-Ethernet flat networking technology is applied to metropolitan area and backbone network. There are tens of thousands of dedicated line services between multiple cities that need to be dispatched, and the aggregation node (like image 3 Aggregation shown) and backbone nodes (such as image 3 The backbone shown) has to manage hundreds of thousands or millions of end-to-end cross-connections, and there are difficulties in management and operation and maintenance. Each core node (such as aggregation nodes and backbone nodes) handles huge cross-connections on the data plane Quantities, difficulties and stress
